  • Course Syllabus: Reminders of class procedures, grading, and assignment types






Monday, September 17th: Families of Linear Functions

Functions in the form f(x) = mx + b are LINEAR.
m is the slope of the line.
b is the y-intercept of the line.
These are the parameters for a line. They determine the shape of the graph.
Classwork: Problem 101 on page 39
Homework: 1.2.3 #105, 106, 108, 110 due Wednesay


Wednesday-Friday, September 12th-14th: Summary Statements

Each group graphed a new function and found the domain and range. (lowest and highest values of x)
We then wrote SUMMARY STATEMENTS to go with each graph. (See examples on page 34 problem 81)
Homework: 1.2.2. # 84-87, 90, 91


Tuesday, September 11th: Points of Intersection
VIDEO NOTES: Points of Intersection Video
You can find points of intersection on any of the representations for functions.
  • Graphs: Look for the points where the two graphs cross each other. Use TRACE on the calculator to estimate the points (x,y).
  • Tables: Look for an x-value that gives the same y-value for both functions.
  • Equations: Set the equations equal to one another and solve for x. Plug in x to solve for y.
Homework: 1.1.4 #47-53 due Thursday 9/13

Monday, September 10th: Domain and Range
  • Domain: The list of all x-values that can be put into a function. (left/right)
  • Range: The list of all y-values that can come out of a function. (bottom/top)
  • ASK: Are there any holes or breaks in the graph?
Homework: 1.1.3 Worksheet #35-41 due Wednesday 9/12


Friday, September 7th: More Function Notation
Homwork: 1.1.2 Worksheet #13-22; 26 due Monday 9/10 see www.cpm.org for the problems under HOMEWORK HELP

Thursday, September 6th: Function Notation
f(x) = y is notation that names an equation, input and output. "f" is the name of the equation, x is the input, and y is the output.

Example: If f(x) = 2x - 3
f(4) = 2(4) - 3
=8 - 3
= 5
4 is the input (x); 5 is the output (y or f(x))

Wednesday, September 5th: Team Problem Solving

We did a team activity that helped us practice the four roles and learn to work as a team.
